Located deep in a desert wasteland, The Nexus Tower holds the means for instant travel to other lands and locations via teleportation portals. Can the tower only be found or accessed by those who are worthy? Do the portals require special components or incantations to be activated, and does each one lead to a different location? Or are the circular ones outbound and their coloured counterparts inbound, or vice versa? Do the locations remain fixed, or do they randomly shift, sending unsuspecting travelers far from their intended destination?
